About


WALLTURB is a European project funded by the European Community Under the 6th Framework Program.
WALLTURB is a Consortium of 16 partners from 10 different countries (9 European and Australia).
WALLTURB has started on April the 1st 2005 for 4 years.
WALLTURB objectives are to assess and better model near wall turbulence.

Objectives

The global aim of the WALLTURB project is to bring in four years a significant progress in the understanding and modelling of near wall turbulence in Boundary Layers. This goes through:

   - generating and analysing new data on near wall turbulence,
   - extracting physical understanding from these data,
   - putting more physics in the near wall RANS models,
   - developing better LES models near the wall,
   - investigating alternative models based on Low Order Dynamical Systems (LODS).

To reach these objectives, the WALLTURB Consortium will take advantage of : - the recent progress in the experimental and numerical approaches of turbulence, - the complementary skills of leading teams in Europe working on turbulence.

It will generate a large and original database, with recent and relevant data about near wall turbulence (from both experiments and DNS already available at the partners). This database will be shared by the partners to extract relevant physical data.

The consortium will also generate new experimental and DNS data, allowing to assess Adverse Pressure Gradient Turbulent Boundary Layer physics, with and without separation, to go in the common database.

This database will be extensively used by all the partners to improve RANS, and LES near wall turbulence models and to develop a LODS/LES coupling near the wall.

The work performed will allow to make available new turbulence models based on a detailed physical characterisation and to assess the relative merits and drawbacks of these models. These models will be assessed by two leading industrial in the field of aeronautics.
